adcphotography Offline Image Upload: Off p.1 #1 · unwanted halos i have this image of the memphis bridge. Nikon D300 with 17-55/2.8 ISO 200 f/10 exposure compensation +1/3 i have sharpened it a little, put a high pass filter on it and an dulled the color a little with an adjustment layer to match other images in the collection (this is 1 in 3 of "memphis icons"). however there are some almost purple-y halos around the lights on the bridge. this is going to be a 16x20 canvas and don't want those to be so prominent. anyone have any advice as to what i should do to rid/minimize them? thanks, amydale Aug 16, 2008 at 01:30 AM

Lose the purple and make the sky and water more green. Masking could limit the area of green adjustment, but it would be a task. Aug 16, 2008 at 11:32 AM

paulhodson Offline Image Upload: On p.1 #3 · unwanted halos I tried increasing the blue saturation in Lightroom and then messed about a bit with Color Balance and Hue Saturation in CS2. Reduces the effect a little - but of course also changes the image somewhat. Original and edit Aug 16, 2008 at 04:50 PM

Bob Jarman Offline Image Upload: Off p.1 #5 · unwanted halos Using Capture NX2, I bumped up the chroma in LCH and then using a color control point globally, adjusted color (deep blue) to try to restore to original (at least close but then my eye isn't the greatest either). I think if you have the NEF you can probably come closer to removing the halos... Bob Edited on Aug 16, 2008 at 06:29 PM Aug 16, 2008 at 06:28 PM

AuntiPode Offline Image Upload: On p.1 #6 · unwanted halos Another PS sequence to try: new adjustment layer>selective color>red>cyan + 80-90% This kills a significant part of the purple cast without changing the color of the sky or water. It does lose a bit of red in the horizon. Aug 16, 2008 at 09:52 PM

AuntiPode Offline Image Upload: On p.1 #8 · unwanted halos Indeed, but masking the horizon should be a simpler task than trying to mask the lights. Aug 17, 2008 at 10:44 AM

paulhodson Offline Image Upload: On p.1 #9 · unwanted halos You misunderstand me - I meant that it would be easy to mask the horizon Here is another idea. Select the highlights (Alt.Control,shift ~), invert and then use the clone tool set to darken to blend the sky over the halos. This is done quickly and not fully - you could fiddle a lot more with the selection/and or masking to get the final effect right. Edited on Aug 17, 2008 at 03:29 PM Aug 17, 2008 at 11:19 AM

AuntiPode Offline Image Upload: On p.1 #10 · unwanted halos Actually, I was agreeing with you Paul. I referred to my previous notion of masking to only change the areas with purple tint to limit the extent of the change. There are so many ways to do some things in PS, I always wonder how many better ways I'd have if I knew it better. Aug 18, 2008 at 06:13 AM

paulhodson Offline Image Upload: On p.1 #11 · unwanted halos According to "The Hitchhiker's Guide to the Galaxy" - the answer is 42. Seems about right to me Edited on Aug 18, 2008 at 06:38 AM Aug 18, 2008 at 06:38 AM

adcphotography Offline Image Upload: Off p.1 #13 · unwanted halos thank you guys so much! i really appreciate you all taking the time to try it out yourself and post your ideas. in the original image, there were no halos. bright and colorful (very close to Bob's version). they appeared after making the picture have a "grungier", muted look. after a couple hours trying out tons of ways, i finally got them to tone down. y'all rock!
